LOCK.

SPECIFICATION forming part of Letters Patent No. 722,619, dated March 10, 1903.

Application fusa september 23,1901. serai No. 76,310. (No man.)

To @ZZ whom t may concern:

Be it known that I, BYRONPHELPS, a citizen of the United States, residing at Seattle, in the county of King and State of Washington,have invented a new and useful Lock, of which the following is a specication.

My invention relates to locks, and particularly to a class of locks wherein the mechanism is contained within a single frame and adapted to be inserted in a notch in the stile of a door; and the object of my invention is to improve the construction of the same.

Simplicity of construction and effectiveness of operation are among the advantages attained in the present invention.

Figure lis a plan view. Fig. 2 is a side View 0f Fig. l, partly in section, looking in the direction of the arrow. Fig. 3 is a detail of a portion of the mechanism in one position. Fig. 4 is a detail showing the mechanism in another position. Fig. 5 is a detail showing the mechanism in still another position. Fig. 6 is a detail of detached portions. Fig. 7 is a detail. Y

Referring to the drawings, A is a frame formed, preferably, of one piece and of a construction substantially as shown and described in a former patent of mine,No. 631,432.

B B' are extensions from the frame A, and journaled therein are hollow rotatable spindles C C', which are provided with suitable knobs D D', respectively. These knobs are preferably hollow, and in one of them, DQ is contained a key mechanism E. (Shown in dotted outline in Fig. 2.) This key mechanism rnay be of the pin-tumbler type well known in the art and will not, therefore, be further described.

F is a draw-rod, one end of which is slidably connected with the key mechanism E. Closely adjacent the knob D is a knurled collar G, having a cam-face G.

G2 is a pin carried by the rod F and in engagement with the cam face G. G3 is a spring which forces the rod F in a direction to cause the pin G2 to bear against the camface G. It will be seen from the foregoing that the rod F may partake of alongitudinal movement when the collar G is rotated, and

it may also partake of a rotary movement when the key mechanism F is operated.

H is a roll-back rigidly mounted in the end of the spindle C.'

J is a roll-back slidably mounted in the spindle C. The roll-backs H and J both have central openings, through which the rod F passes, so that the latter may partake of its rotary movement without actuating the rollbacks.

Fastened in the rod F is a pin K, which sweeps against one side of the roll-back J.

L is a collar on the rod F, bearing against the opposite side of the roll-back J. The collar L has a curved tongue L', which takes into a notch in the rod F and which holds the collar' from slipping on the rod F.

C2 is a notch in the end of the spindle C', in which the roll-back J may slide.

B2 is a notch in the frame A, which registers with the notch C2 in the spindle C when the spindle is in normal position.

M is a latch-bolt.

N is a yoke having a shank O, which latter is pivoted to the latch-bolt M.

Pis aspring which holds the latch normally, as shown in Fig. 3.

The roll-back H may normally engage the yoke N. Therefore the latch may be retracted by turning the inner knob D. When the collar G is rotated upon the spindle, the rod F is moved longitudinally and carries the rollback J into the notch B2 in the frame. This locks the outer knob D from rotation.

R is a bolt having a shank R', which is slidably mounted in the frame A. The shank R has a groove R2.

S is a rock-shaft pivoted to the frame A. S is an arm projecting from said rock-shaft which carries a pin S2, which pin engages the groove R2. When the shaft S is rocked, the pin S2 bears against one side of the groove R2 and moves the bolt R.

T is a finger-piece for rotating the shaft S. The bolt may also be thrownby the key mechanism about to be described, but as will be seen it may be thrown by finger-piece T at any time independently of the said key mechanism.

F and F2 are actuating-dogs, Fig. 7', mounted on a hub F3. The hub F2 has a square opening through which rod F freely slides. When rod F is rotated, the hub F3 is also r0- tated and with it the dogs F and F2.

V is a reach-rod having projections V' and V2, adapted to be acted upon by the dog F. One end of the reach-rod V is pivoted to an arm S3 of the rock-shaft S. Carried by the reach-rod V is a dog V4, which is springpressed against a pin V5. The projections V' and V2 are in the path of movement of the dog F', while the dog V4 is in the path of movement of the dog F2.

S4 is a flat spring bearing against faces of the rock-shaft S, and serves to hold the latter in its extreme positions.

Assume that knob D' is locked and that bolt R has been thrown out by finger-piece T. In order to throw the bolt in, a key is inserted in the key mechanism and turned until the dog F' is moved into contact with projection V2. Continuing the rotation of the key the dog F' bears against the projection V2 and throws the bolt R into the position shown in Fig. 4. Still continuing the rotation of the key the dog F2 presently comes into contact with the dog V4 and moves the same, and as dog V4 bears against yoke N the latter is moved, thereby compressing spring P and retracting the latch ll/I. The parts now have the position shown in Fig. 5.

It will be seen that locking may be effected by throwing the bolt R or by turning collar G and locking knob D', or by both. When only the knob D is locked, the mechanism is in position, as shown in Fig. 4, and the key mechanism is free to turn the hub F3 until dog F2 operates the yoke N through dog V4. When the bolt R is thrown and the knob D not locked, the key mechanism throws back the bolt R, at which time the latch mayv then be retracted by further turning of thekey or by rotating knob D' by hand.

By making the arm s3 shorter than the arm s2 I secure a suiciently long movement of the bolt R with a minimum rotation of the key. l

It will be observed that when the bolt R is out and the rock-shaft in position shown in Fig. 3 the pin S2 is about on a line with the bolt R and the axis of rotation of the shaft S. This prevents any movement being given to the shaft S from bolt R and holds the latter locked.

Obviously many changes may be made in the particular construction herein shown without departing from the spirit of my invention.
